目的分析腰肌病变累及肾旁后间隙的CT表现,探讨其侵犯途径和解剖学基础。方法回顾性分析21例CT扫描资料和临床资料完整的腰肌病变累及肾旁后间隙的连续性病例,其中经手术病理证实15例;经临床综合指标及抗炎治疗随访显效而诊断者6例。着重观察:①腰肌病变累及肾旁后间隙的CT表现;②腰肌病变累及肾旁后间隙的途径。结果①肺癌腰肌转移2例,肝细胞癌腰肌转移1例,胃癌腰肌转移1例,腰肌肉瘤1例,腰肌黏液腺癌1例,淋巴瘤侵犯腰肌1例,均为单侧;腰椎结核并腰肌冷脓肿10例,其中5例为双侧;腰肌脓肿4例,均为单侧;②腰肌病变累及肾旁后间隙的途径为:直接侵犯同侧肾旁后间隙或先侵犯同侧肾周间隙后突破肾后筋膜侵犯肾旁后间隙或两种方式混合出现;③腰肌病变累及肾旁后间隙表现为:与腰肌病变相连的肿块影;肾旁后间隙内结节影、索条影;肾旁后间隙内密度增高;肾后筋膜增厚。结论CT可准确显示腰肌病变累及肾旁后间隙的解剖学细节。
Objective To analyze the CT manifestations of renal parenchymal space involved in lumbar myopathy and explore its invasion and anatomy. Methods A retrospective analysis of 21 cases of CT scan data and clinical data integrity of the patellofemoral lesion involving the retroperitoneal space continuity cases, of which 15 cases were confirmed by surgical pathology; clinical indicators and anti-inflammatory treatment were followed up were effective and 6 cases were diagnosed . Focus on: ① lesions involving the renal patellofemoral space after the CT performance; ② pituitary lesions involving the renal pathway after the gap. Results ① There were 2 cases of lumbar metastasis in lung cancer, 1 case of lumbar metastasis of hepatocellular carcinoma, 1 case of metastasis of lumbar muscle in gastric cancer, 1 case of lumbar myosarcoma, 1 case of mucinous adenocarcinoma in pituitary gland and 1 case of lymphatic invasion of psoas. Side; lumbar tuberculosis and lumbar cold abscess in 10 cases, of which 5 cases were bilateral; lumbar muscle abscess in 4 cases, both unilateral; ② pyloric lesion involving the pathways after the paraventricular space: direct violations of ipsilateral renal side The gap or the first ipsilateral ipsilateral renal peritoneal space after the break through the renal fascia invasion of the perineum or after the gap between the two ways of mixing; ③ pyloric lesions involving the renal side of the gap as follows: connected with the lumbar lesion mass; After the nodules in the gap shadow, cable shadow; renal density after the gap increased; after the fascia thickening. Conclusion CT can accurately show the anatomical details of the lesion involving the paraventricular space.
